What is the terminal velocity of a falling cricket ball and how high would it need to be hit in order to reach that velocity?
As an avid experimenter and paraglider pilot the question of how fast an object reaches terminal velocity has been tested a few times by our fellow pilots.
In fact one 'person' actually hollowed out a cricket ball and installed a miniture vario to record the 'flight curve'.
The ball was re-weighted to allow for the hollowed out section so it was the same as an un holled ball.
Air density was 1013-1011 during the half hour flight.
Altitude dropped from was 2000ft above field.
Max speed came out at a little over 35m/s ( about 80mph).
Interestingly the speed did vary 3 or 4 mph during the terminal velocity period.
We put that down to the ball turning and the seam presenting itself in different angles to the air flow and changing the Cd. (also it was an oldish slightly scuffed ball, so maybe a new polished one may travel a few mph faster)
Thats the closest I get to cricket !
Hope this info is of use to some of the out fielders.
Im off to find another cloud.

What is the order of passageways from proximal to distal?
The order of passageways from proximal to distal in the human body is typically mouth, esophagus, stomach, small intestine (duodenum, jejunum, ileum), large intestine (cecum, colon, rectum), and anus.
What the stages of a plotline in their correct order?
The stages of a plotline typically include exposition (introduction of characters and setting), rising action (development of conflict), climax (turning point or main conflict), falling action (resolving the conflict), and resolution (conclusion or ending of the story).
Why can't specialised cells divide?
Specialized cells, unlike stem cell, cannot undergo mitosis or cell division. Through terminal differentiation, specialized cells gave up their ability to divide in order to do one specific function.
Why do we have to close our eyes in order to sleep?
Closing our eyes helps signal to our brain that it is time to rest and sleep. When we close our eyes, it reduces the amount of light entering our eyes, which helps trigger the release of the hormone melatonin, which is important for regulating our sleep-wake cycle. Additionally, closing our eyes helps our brain relax and focus on internal processes that are necessary for falling asleep.

Why is it difficult to calculate the terminal velocity for a cat falling from a high rooftop?
Calculating the terminal velocity for a falling cat is challenging because it involves a complex interplay of factors such as the cat's shape, orientation, and surface area. The cat's movements and aerodynamics during the fall also affect its terminal velocity, making precise calculation difficult. Additionally, ethical considerations prevent conducting experiments that could provide accurate data on this scenario.
The point at which an object is falling at the fastest it can go is called its velocity?
When objects fall gravity causes them to increase their speed. The speed would continue to increase if there was no atmosphere. But the atmosphere causes friction which prevents the object from continually increasing its speed. At some point in the fall the object reaches what is called its "terminal velocity". This is the maximum speed it reaches when the frictional force prevents it from going any faster. The terminal velocity of falling objects depends on their shape and mass so it is different for different objects. Also some objects take a long time to reach their terminal velocity so they have to be dropped from very high up in order to have time to reach terminal velocity before hitting the ground.
Why does a heavy sky diver have a terminal speed greater than a light sky diver?
Terminal velocity is when air drag stops you from going any faster when falling. A heavier person will fall with greater force than the light sky diver falls at. So the heavier skydiver will require more force from air in order to keep him/her at terminal velocity
What two Forces Have to Be equally strong in order for a falling object to reach terminal velocity?
The force of gravity pulling the object downward must be equal to the force of air resistance pushing upward on the object. When these two forces are balanced, the object stops accelerating and reaches terminal velocity, where its speed remains constant.
How does the velocity of a falling object change over time?
The velocity of a falling object increases as it falls due to gravity. However, as it continues to fall, air resistance will cause the object's velocity to eventually reach a terminal velocity where the forces of gravity and air resistance are balanced, resulting in a constant velocity.
When a body attains terminal velocity its drag force and gravitational force on body cancels each other then why does the body still comes down instead of floating?
When the gravitational and drag forces on the object are equal, there is no net force acting on the object. This means that the body will not accelerate; it will not change it's velocity.In order for the body to slow down to "floating speed", the drag force would have to be greater than the gravitational force. Drag force is dependent on velocity though, so the greater the velocity the greater the drag. Since the body is not accelerating at terminal velocity, it won't increase it's velocity, and therefore the drag force on it will not increase.(This is all assuming that is a rigid body in an atmosphere with a more or less uniform density, such as a block falling from an airplane.)
The downward force of gravity and the upward force of air resistance on a ball?
0 meters per second squared As stated above, the ball will have zero acceleration due to the equal upward and downward forces, presuming the ball is moving or attempting to move in an upward or downward direction. The ball, in fact, will not be moving at all in this situation, but will be suspended in its position. If you are referring to an acceleration or motion in a direction that is not vertical, you will need to provide other information in order to get an answer.
Why are cricket balls stitched?
Cricket balls have an outer cover made of four pieces of leather. In the old days, such coverings had to be stitched in order to keep them from falling apart while in use. The stitched seam continues to be on the cricket ball today because it has become an important aspect of bowling technique.
How far up in the air do you have to be in order to fall for an hour?
It will be somewherebelow 160 km from earth surface since average human terminal velocity is 160 km/hr. More detail calculation would be needed since at that height, gravity would reduce by 0.4 m/s2 and air is so thin that it had little friction and terminal velocity might be very high at that height.
Does gravity pull things down 32.2 feet per second?
Absolutely Not.Gravity is NOT a pulling Force. Gravity is a "Pushing" Force of Mass Expansion.Earth Mass is Expanding at the Gravitational Acceleration rate of 9.808175174 m/s^2In order to understand you must first accept the Mathematics on EinsteinElectricitydotcom because Math does not lie. Then you can move on to EinsteinGravitydotcom.Acceleration due to gravityNo. There is a difference between speed (or velocity) and acceleration. They are, of course, related, but acceleration is the rate of change of velocity. When you are sitting in your car at a red light and the light turns green and you step on the gas (or accelerator!), your car accelerates from zero to some final velocity (hopefully not much more than the posted speed limit). Your speedometer clearly shows the change in velocity as the needle moves clockwise. The faster that needle moves, the greater the acceleration.On Earth, objects do not fall at constant speed, as your question suggests. Gravity accelerates objects toward the center of the Earth at 32.2 ft per second per second (which can also be written as 32 ft/s2). In other words, an object's velocity will increase by 32.2 ft/s (or 9.8 m/s) for each second the object falls until it reaches its terminal velocity, which you can think of as a kind of speed limit. Terminal velocity is reached when air friction equally opposes the force of gravity. Different objects will have different terminal velocities, depending upon their shapes.More discussionImagine you are on top of a tall building and holding a bowling ball over the side of the building. At time t = 0 seconds, you let go of the ball. At that exact moment, the ball is traveling at 0 ft/s, but as the ball experiences gravity without your holding it, it starts to fall. After one second, the ball will be traveling 32.2 ft/s. After two seconds, it is traveling 64.4 ft/s, and after three seconds, it is traveling at 96.6 ft/s.So you see that falling objects do not fall at the constant rate of 32.2 feet per second but actually accelerate -- that is, pick up speed -- at a rate of 32.2 feet per second per second.Note: The equation of rectilinear motion can be found at:Uh, Update: This article doesnt seem to mention "terminal velocity." Eventually, a falling bowling ball will not continue to pick up speed, it will reach Terminal Velocity, and stay at that speed. Terminal velocity is reached as the air resistance on a falling object approaches the momentum of the object. For example, as a bowling ball falls, gravity makes it accelerate at 32.2 feet per second. The bowling ball also hits air molecules, which slows it's acceleration. This is air resistance. As the bowling ball falls faster, more air molecules hit it per second. This is because the bowling ball travels a greater distance per second and passes through more air, and more air molecules. Eventually, the combined forces of all of the air molecules negate the acceleration of the bowling ball. At this point the bowling ball neither accelerates nor decelerates, it reaches an equilibrium. It will keep falling at a constant speed: its terminal velocity. If it were to somehow fall faster than its terminal velocity, the extra air molecules that hit it would actually slow it down until its terminal velocity was once again reached.An object's velocity, then, is determined both by its weight and its shape relative to the ground. If an object is small, like a bowling ball, it does not pass through many air molecules per second, and must travel faster to hit enough air molecules per second to reach terminal velocity. If an object's surface area is large, like a parachute, it does not need to be traveling as fast in order to hit enough air molecules per second. yep your right agree subscribe
